Tissue Engineering and Cell-Based Regenerative Therapy

The center was established in the year 2009 under the supervision of Prof. Hanan el Baz (Professor of Immunology, TBRI) and it consists of 6 units:

1) Clinical Research Unit:

A clean lab prepared for clinical translation and applications of stem cell research. It consists of and 4 areas:

­Area A (under the laminar flow): the most sterile area. It is used for isolation and culture of stem cells.

­Area B (Working area):

  •  This area is for processing of samples.
  •  Benches are made of electro polished stainless steel.
  •  This area is equipped with:
    1.  Clini MACS (Miltneyi Biotech, Germany): closed system used for clinical separation of different types of cells from bone marrow aspirate and leukapharesis.
    2.  Sepax (Biosafe, Spain): closed system used for separation of mononuclear cell layer from blood samples.
    3.  Co2 incubator (Thermo Scientific, USA).
    4.  Cooling centrifuge (Eppendorf, Germany).
    5.  Laminar flow (Telstar, Spain).
    6.  Balance.
    7.  Shaker.

­ Area C (Preparation area):

  •  Contain benches and storage units made of electro polished stainless steel.
  •  This area is equipped with:
    1.  Ordinary microscope (Olympus, Japan).
    2.  Inverted microscope (Olympus, Japan).
    3.  Digital camera with adaptor for ordinary and inverted microscopes (Olympus, Japan).
    4.  Refrigerator.
    5.  Labtop.

­ Area D (Gowning area): contain step over bench, lockers, and unit for storage of sterilized gowns. They are all made of electro polished stainless steel.

Area E (hand sterilization area).

2) Experimental Research Unit:

­ Equipped with:

  •  Laminar flow (Telstar, Spain).
  •  Co2 incubator (Thermo Scientific, USA).
  •  Cooling centrifuge (Eppendorf, Germany).
  •  Ordinary microscope (Olympus, Japan).
  •  Inverted microscope (Olympus, Japan).
  •  Refrigerator.

3) Sample Preparation and Characterization Unit:

  •  For paper work and documentation.
  •  Characterization by Flowcytometry (Beckman Coulter) in the central lab of TBRI.

4) Molecular Immunology Unit:

­ For molecular characterization of stem cells.

­ Equipped with:

  •  Laminar flow (JSCB 1200SB, Korea).
  •  Real-time PCR (Applied Biosystem step one, USA).
  •  Thermal cycler (Bio-Rad, USA).
  •  High speed cooling centrifuge (Eppendorf, Germany).
  •  Spectrophotometer (ABBOTA, USA).
  •  Gel electrophoresis.
  •  UV transilluminator.
  •  Microwave.
  •  Laptop.

5) Cryopreservation Unit:

­ For storage of cells and tissues in liquid nitrogen (-200).

­ Equipped with:

  •  Liquid nitrogen tank: as a reservoir for liquid nitrogen.
  •  2 Liquid nitrogen locators with racks (Thermo Scientific, USA): for storage of samples.
  •  Controlled-rate freezer (Thermo Scientific, USA).


– For storing sterile disposables.
